HOOK r03 use WITH CHAINS.

' Application filed April 18,

for spoked vehicle wheels, so that such chains can be convenientlyapplied or removed and when applied shall be retained securely in place.This and other objects of my invention, will be more fully made apparentin the following specification and claims taken in connection with theaccompanying drawings in which I have disclosed two specific embodimentsof the invention. It will be understood that modifications may be madewithin the scope of my invention as stated in the claims.

' Referring to the drawings, 7 v

Figure 1 isan elevation of my improved hook in engagement with a chainlink;

Fig. 2 is a side elevation of the same hook; 1

Fig. 3 is an end elevation looking in the direction of the arrow 3 inFig. 2;

F i' 4 is a section t ken on the line 4-4: of Flg. 2, and l Fi 5 is anelevation of a modified form in w 'ch my inventive idea may be embodied.Y

Referring to'the modification shown in Figs. 1 to 4, the hook has an eye11 at one end 16 adapted to be permanently engaged by the end link of achain. Adjacent to the eye 11 is a shoulder 12 with the part 13overhanging the .ti 1501 the hook. Connected with'the en portion 16 isthe .proxi mal portion comprising the neck 17 and'the part 21; thencomes" the-apex 23, beyond which is the'distal portion comprising the lparts 19, 18, andth'e tip .15. The projecting abutment 20- overhangs thelink 24: when I 'the link 24:

the hook and thelink' are fully assembled,

n -at this time in the notch,

or socket'22."

Betweenitheti :15 and the face 13 of the i shoulder'12; is 't e openingto receivethe link in assemblin the chain withv the link. Extending fromt opening is a reversely Specification of Letters Patent.

curved or S-shaped passage 14 which termlnates at the socket 22.

The abutment 20 is of considerable width as shown in Fig. 1 so that anlar movement of the chain link 24 is hmited relatively to the hook aboutan axis perpendicular to the plane of the drawing. The abutment '20 alsoaids materially in keeping the link 24 securely engaged by the hook.

- The passage 14; is reversely curved as shown, in order that thelinkmust be turned through a considerable angle first one way and thenthe other way in order to remove it from the hook. This will be apparentPatented May 11, 1920.

from a consideration of Fig. 2. To remove the link 24: it would have tobe turned clockwise to bring it to the position .24 and thencounter-clockwise to remove it entirely from the tip 15 of the hook." Itwould be extremely unlikely that such movements could be effectedaccidentally so that the security of engagement of the hook with thechain will be assured. It is to be noticed in this connection that thechannel 14 is of approximately uniform width and only enough wider thanthe thickness of the chain stock to provide proper clearance.

The line a-b drawn so as to touch the parts 19-and 12 of thehookliesoutside the j tip part 15 as shown in Fig. '2'.' Accordingly,the tip 15 will be protected from a blow delivered by any large object,which will be received at 12 or-19 or at both points together, but noton the tip 15.

. To a very great extent this will prevent the tip 15 from being bent.If a very heavy blow is delivered against the part 19, or a suiiicientlyheavy' blow by a small object against the tip 15, the only efiect willbe to close the passage 14 and lock the hook in engagement with thechain; evidently so far as this involves any failure of the apparatus'it will be on the side of safety.

Referring to the modification shown in Fig. 5; this is made of a uniformsize stock steel rod 'bent'to the'shapel's hownin the drawing. I Thereference characters primed.

have-been applied in ;a manner to correspondto Figs. -1 to 4...Thepassageili' is of. substantially uniform width; enough greaterthanthe thickness of the .chain stock ing'member- 20' performs the'samection a the e m ed element in Fig. 2 in hinderin the escape of the hookfrom the chain lin with which it may be in engagement.

I claim:

1. A book having a slot to receive the linkof an anti-skid device to besecured, and a transversely wide projection projecting into said slot tocause said link to be at substantially right angles to the plane of thehook passing through the opening in said link. '2. A book for ananti-skid device having a base portion and a proximal portion and a tipportion extending therefrom, said tip portion being formed by reversecurves 23, 19, 18 and 15 connected end to end substantially in the formof an 5 so as to tip the link in opposite directions as it passes alongsaid tip.

3. Aflhook adapted to cooperate with the links ofzan anti-skid devicefor vehicle wheels, comprising a base portion and a tip portionextending therefrom, and providing reversely curved surfaces spacedrelatively to the link surfaces to tip said link'first in one directionand then in another as said link passes along said tip portion.

4. A hook adapted to cooperate links of an anti-skid device for vehiclewheels, comprising a base and a proximal portion and a tip portionextendin therefrom, said tip portion being fo'rme by reverse curvesconnected end to'end substantially in the form of an S and being of onlyslightly less thickness than the Width of the opening in said link.

with the 5. A hookadapted to cooperate with the links of an anti-skiddevice for vehicle wheels, comprising a base and a proximal portion anda tip portion extending therefro'm, said tip portion being formed byreverse curves connected end to end substantially in the form of 'an Sand being spaced from said base and proximal portions by a reverselycurved slot.

r 6. A hook having a base and-a curved portion with parts proximal toand distal from said base, an abutment projecting across from theproximal part toward the distal part said hook being adapted tocooperate with a link engaged thereby and of stock substantially fillingthe space between said abutment and the apex, said abutment beingtransversely wider than the apex part of the hook.

7. A hook having a base and a curved portion with parts proximal to 'anddistal from said base, the distal part being curved relatively totheproximal part so as to be convex toward the proximal part and anabutment projecting across from the proxi-, mal part toward the distalpart near the apex so as to form a reversely curved pasabutment on oneside and the distal part on the other side said hook being adapted tocooperate with a chain of links each having an opening slightly greaterthan the thickness of the distal part of the hook.
